Egor Savkin 21fc244eac Fan status via quadratic regression 
* statuses: detect slow fan via quadratic regression and halts (hard stops) with constant threshold
* remove unsafe channels' copy and make FanCtrl own the channels
* scale fan values so that they would fit 0.05-1.0 PWM at all times
* rename fan-restore to fcurve-restore
* style, names and docs adjustments

topquark12 26ad2f0119 rewrite PID 
Rewrite of PID according to https://hackmd.io/IACbwcOTSt6Adj3_F9bKuw PID implementation.

To migrate:
- TEC+/- pin polarity has to be reversed.
- Some saved settings might be wiped upon flashing of new firmware, back up settings before upgrade
- Min / Max integral parameters no longer exist
- kp, ki, kd will likely need to be retuned

The software has been tested on hardware with good temperature control stability.

topquark12 7c013ff4a4 PID fixes 
Flipped error calculation method to correct behavior of kP and kI terms.

Added anti integral windup to integral handling.

Changed how the i and integral term is calculated, to prevent old kI settings from affecting the current i term calculation when kI is being tuned. Especially noticable when kI is set from a non-zero value to zero.
